HMD Display Control Device for Dynamic Object Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted display (HMD) users experience discomfort due to stationary display objects blocking their field of view, as these objects are constantly displayed at fixed positions on the display surface.
Innovation Solution
A display control device and method that moves displayed objects on the HMD screen in accordance with the movement of the device, automatically relocating them to a predetermined position without user input, using sensors like acceleration, gyro, and geomagnetic sensors to detect movement and adjust the display accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If display objects are constantly displayed at fixed positions on the display surface, then the display objects remain visible and accessible, but the user's field of view is blocked and the user feels discomfort
Solution Approach 1:
The display object's position is changed from static to dynamic. The object automatically moves to a predetermined position when the user moves their head, making the display adaptive to user movement while maintaining visibility and reducing field of view blocking.
Solution Approach 2:
The display system automatically detects user head movement and repositions display objects without requiring user interaction. The system serves itself by using sensor data to autonomously adjust the display, eliminating the need for manual intervention.
2Object-affected harmful factors
If display objects move with device movement, then the field of view is not blocked and user comfort improves, but the display objects may become difficult to locate
Solution Approach 1:
The display object is pre-configured with a predetermined return position. When the user moves their head, the object automatically returns to this predetermined position, ensuring it remains locatable while still moving with device movement during the transition.
Solution Approach 2:
The system uses sensor feedback to detect user head movement and automatically adjusts the display object's position accordingly. This closed-loop control ensures the object moves appropriately with device movement while maintaining user awareness of its location.

AI summary
A device may include a display control unit to move a displayed object on a screen of a display device according to movement of the display device. The displayed object is moved to a predetermined position on the screen after the display device stops moving without any user input.
